Posted by JustAnswer at customer's request) Hello. I would like to request the following Expert Service(s) from you: Live Phone Call. Let me know if you need more information, or send me the service offer(s) so we can proceed.

What I usually see as the most common issue for these not running in hybrid mode is an issue with the air conditioning. The air conditioning needs to be fully functional for the system to switch to hybrid mode. The system uses the air conditioning to help cool the battery back through the rear evaporator. If the air conditioning is slightly low on freon the pressure could intermittently fall out of acceptable range causing hybrid drive inhibit. That is the most common issue I see for this symptom, other than that the PCM and BCM modules would need to be scanned for faults and depending on what code(s) are stored would determine the next step in diagnosis.

If you are satisfied with your answer, please take a moment to rate my service as you see fit. Experts are not compensated without a positive rating. Providing a rating does not close the question, you can reply or ask additional questions without incurring further charges.

Ok thanks. At this point I would need to know if there are any codes stored in the powertrain control module or the battery control module. There are no other common issues for this symptom other than the A/C.
